Questão jurídica principal
Whether the cantonal authority had to decide the recusal request by a court under Art. 30 BV and Art. 6 ECHR
Decisão extraída
Those guarantees did not apply because the prosecutor was acting as an investigative authority, not in a judicial function.
Fundamentação extraída
A prosecutor or investigating judge is subject to the impartiality guarantee of Art. 29(1) BV, but Art. 30(1) BV and Art. 6(1) ECHR apply only when the authority acts in a true judicial role.
